METHOD OF IVIAKING NUTS AND ARTICLES MADE THEREBY.

Application filed June 29,

To all whom it may concern:

Be it known that HocoF/Sonnonnnn, a citizen of the United States, residing at Torrington, in the county of Litchiield and State of Connecticut, has invented certain new and useful Improvements in Methods of Making Nuts and Article Made Thereby, of which the following is a specification.

This invention relates to a method of making nuts and to the article made thereby. According to the method I can produce in a very slmple and satisfactory manner a highly efficient nut which will properly resist any strains to which it may be subjected in practice and which will be held in a certain manner against rotation.

In the drawings accompanying and forming part of the present specification, I have shown in detail one of the several forms of carrying the method into effect and in said drawings there is also illustrated a form of embodiment of the resultant article. Obviously am in no sense restricted to such disclosure. I may depart therefrom in sev eral respects within the scope of the inven tion defined by the claims following said description.

Referring to said drawings:

Figure l is a front elevation of a blank partially formed.

Fig. 2 is a view as seen from the right end in Fig. 1.

Fig. 3 is an enlarged sectional. detail.

Fig. 4 is a side elevation of the partly formed-up blank.

Fig. 5 is an end elevation of the same as seen for instance from the right in Fig. 4-.

Fig. 6 is a side view of the finished article and Fig. 7 is an end view as seen for instance from the right in Fig. 6.

Like characters refer to throughout the several views.

A nut involving the invention, can be employed with advantage in any of the con nections where those of the ordinary kind are usable, although the same is of particular advantage when employed as part of the equipment of a tool such as a hack saw it being situated in this particular instance, in the handle of the saw and being keyed to a wall of the socket in which it is fitted like parts 1921. Serial No. 481,200.

and having for such purpose an external key or fin extending, preferably throughout the entire length thereof or in the direction of the longitudinal center whether the complete length or not. I

Initially I take a piece of proper sheet stock such as 1 and usually of metal, rolling it spirally as at 2. vVhen the sheet or blank is thus rolled there will be formed upon opposite surfaces of it threads which may be pitched t0 the desired size. At the same time there is desirably rolled on the blank the outwardly-extending wings 3 and 4 which are desirably situated on the external side of the blank as shown in both Figs. 1 and 2. The first step therefore comprises with the aid of suitable dies or otherwise, the spiral rolling of the blank to pro-' duce threads on both sides of the blank and concurrently the formation of the wings 3 and 4 these wings when thenut is finished merely abutting, being not interlocked and presenting jointlythe external key of the nut.

Subsequent to the threading and the winging of the blank in the manner described, it is formed up into U-shape or practically so as shown in Figs. 4 and 5 by dies or otherwise. After the blank has been made into U-form practically as described, it is with the aid of a suitable mandrel or in some proper manner shaped into cylindrical form as illustrated for example in Figs. 6 and 7.

In shaping up the blank from the second to the third step, the side edges of the body 5 of the blank are brought together and merely abut as clearly shown in F 7. At the same time the inside faces of the two wings are brought together or into contact to make the key 6 which as shown extends throughout the complete length of the practically cylindrical nut externally thereof. The wings 3 and 4 merely abut and are not interlocked so that when desired under certain circumstances the nut may expand yet it cannot contract beyond the limits permitted by the abutting of the wings 3 and. 4:

and the side edges of the blank.

It will be clear from the foregoing description that 'he nut is split, the split or edge portions thereof being in abutment and being provlded with wlngs which solely abut against each other on their inner sides to form a key external of the nut-and desirably extending throughout the complete length thereof. Desir'ably thenut is made from sheet metal stock.

that. I claim is 1. A. method comprising rolling athread in a sheet and forming on the sides of the sheet wings, and afterward forming the. rolled-winged-sheetinto,a cylinder with the edges of the sheet and the wings solely in abutment to form an externallysthreaded 3. A nut internally and externally threaded and split, the split portions being in abutment and being provided with wings which solely abut against each other on their inner sides to form a key longitudinally and externally of the nut, and extending throughout the complete lengthlthereot.

i. A nut split throughout itslength, the split portions being inabutment and being provided with wings1 which solely abut against each other on their inner sides to form a. key external of the nut longitudinally thereof. W

In testimony whereof Iallix my signature.
